In the present study, the flow fields generated by two jets with a chevron and a conventional circular nozzle exits are studied and compared. Three different nozzle configurations were considered one with no chevron and the other two has 4 and 8 chevrons each. Each configuration, has been studied with two different exit Mach numbers. Centerline velocity decay and turbulent kinetic energy were analyzed and discussed. It is found that the flow field strongly depends on the exit geometry
